If you’re like most people, you probably have books and e-books stored on your iCloud account. But if you want to delete a book from your account, there are a few steps you need to take. First, open the iCloud app and sign in. Then click on the three lines in the top left corner of the main screen and select “Delete books.” Once you’ve selected “Delete books,” your account will be locked and you won’t be able to add or remove any more books from your account.
